KesadaPrice ofAfter the grouting hole is drilled, the grouting pipe, grout stopper, mixer and other facilities in the hole shall be installed and lowered.
Four advantages of establishing a good cooperative relationship with customers: Professional production equipment and testing facilities ensure the quality of the supplied grouting pipes.
Brosad.In China,BrosadAdvance small conduit for tunnel, the types of grouting pipes are relatively complete now, from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.
The disposable grouting pipe uses steel springs as the supporting framework, and is wrapped with a layer of non-woven filter cloth. The outermost layer is wrapped with nylon mesh, and can only be grouted once.
.Introduction to the advantages of grouting pipe: Simple installation, complete supply; The grouting pipe can be cut at the construction site according to the actual required length of the joint (it is recommended that the longer grouting outlet length should not exceed 6m); No special installation equipment is required; Grouting time can be arbitrarily selected; When grouting is carried out internally under proper pressure, the grouting pipe fluid can keep filling the whole pipe evenly; The system allows grouting under relatively low pressure; The grouting pressure is 0.2-0.4mpa; The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed.
The grouting can be repeated many times.
Advantages of grouting pipe grouting pipe is an embedded grouting pipe system, which is used for permanent sealing of construction joints, pipe seepage joints, and gaps between ground walls in concrete. It is very suitable to install grouting pipes between the joints of new and old concrete. When water penetrates into the joint it can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way.
Cut and cut the spring skeleton grouting pipe according to the components. The cutting surface must be flat and free of burrs. The length of its flat section must be ≥ the connecting reinforcement measures. During the bending process of the grouting pipe, it is not allowed to use a small one. The inner diameter of the grouting pipe is compressed and cracked. The alignment between M and FL is 45-56
In the engineering practice,Brosad42 small catheter, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, and forbid vehicles to swerve, brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between 560. Therefore, the relative displacement trend or relative displacement will occur between the narrow two, which will then generate friction. This friction is generally called &surface friction&.
Features: the grouting pipe is divided into disposable grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe).
Welcome calls .The installation will not affect the characteristics of the building grouting pipe itself; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed; Ccll-y series grouting pipe: grouting once, not reusable ccll-d series grouting pipe: multiple times of grouting, grouting is not limited by time.It is applicable to waterproof joints of subway, tunnel and basement. If there is water leakage grout can be injected into the pipe body to fill and seal. It is very suitable to install grouting pipes between the joints of new and old concrete. Various materials such as cement slurry, the joint can be sealed by injecting slurry into the PVC port or spring skeleton port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way.
It is a kind of embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints and gaps between ground walls in concrete.

When water penetrates into the joint it can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way. Injecting grout into the embedded grouting pipe can seal construction joints, cold joints, pipe leakage and joints between the ground walls.

If there is water leakage, grout can be injected into the pipe body to fill and seal. It is very suitable to install grouting pipes between the joints of new and old concrete. Various materials such as cement slurry, polymer slurry and polyurethane chemical slurry can be injected. When water penetrates into the joint, the joint can be sealed by injecting slurry into the PVC port or spring skeleton port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way.
Slump test shall be carried out for concrete entering the site. No less than 3 groups of test pieces shall be made for the same batch of concrete with the same strength grade. One group is used for standard curing, and the other two groups are used for curing under the same conditions to determine demoulding and allowable lifting time.
Price.The grout stop plug used in the grout stop plug grouting method is the key device to seal the grouting borehole and realize segmented grouting. A good grout stop plug should ensure normal operation under the grouting pressure of more than 10MPa. According to its structure and working principle, the currently used slurry stoppers can be divided into two types: mechanical type and hydraulic expansion type. Among them, mechanical slurry stoppers are relatively simple and reliable, and are widely used. 21-5 is one of several commonly used slurry stoppers.
Low cost, fast time, no loss, free from climate and place constraints.
When reinforcing collapsible loess, sodium silicate solution with 5% sodium chloride and concentration of 10% ~ 15% is used. After the solution is pressed into the soil layer sodium ions will react with calcium ions in water-soluble salts of the soil to form silicic acid gel between soil particles and on their surfaces, increase the cementation between soil particles, and harden the soil. The ultimate compressive strength can reach 0.2 ~ 0.8MPa. When strengthening the silty fine sand, a certain amount of phosphoric acid (density 0 is added to the sodium silicate solution (density 18-2 with a low concentration. The solution is chemically reacted in the soil to harden the soil, and its ultimate compressive strength can reach 0.4-0.6mpa.
Brosad.Grouting pipe is a tubular waterproof sealing material used for grouting of concrete construction joints.
When lifting and demoulding components, the non prestressed members shall not be less than 50% of the designed standard value of concrete cube compressive strength, and the prestressed members shall not be less than 75% of the designed standard value of concrete cube compressive strength.
Full section slurry discharge (4 slurry discharge holes) is uniform and smooth.
